20140901 Sun

This morning, I replaced the tap of my toilet... this is a long outstanding issue, but it's finally fixed.  So here we go for solar imaging again!

Seeing 3/10, transparency 7/10 with so many cloud around, so I couldn't do mosaic... I really want to do a big sun again soon!

First up is a near full disc at 1347 (GMT+8), the monster filament is the eye catcher!   Here are the active regions from the left to the right: AR2152, 2153, 2151 with 2149 close to the left limb.

So the next step is to capture a close up of the monster filament with a 2x barlows, the camera was rotated to align with the diagonal of the CCD chip, taken at 1349 (GMT+8):-

Going up to 5x for some more close up, at 2400mm with a small 1/3" CCD, poor seeing reveals no fine detail, taken at 1355 (GMT+8):-

AR2151 at 1358 (GMT+8):-

AR2152 at 1402 (GMT+8):-

AR2149 at 1404 (GMT+8):-

Finally, a three frames mosaic of the monster filament at 2400mm from 1359-1401 (GMT+8):-

Moving cloud renders uneven illuminations.
